480W, 960W three-phase ac-dc DIN rail power supplies deliver +50% boost power rating

TDK CORP. TDK-Lambda DRB series of DIN rail mount power supplies are available in three-phase AC input models with 24V, 48V and 72V outputs. Products are rated for continuous operation at 480W or 960W and can deliver a boost of 720W and 1440W respectively for up to seven seconds. This, and a constant current overload characteristic, enables operation with capacitive and inductive loads. Power supplies provide a low energy inrush current upon initial start-up, reducing nuisance tripping of input circuit breakers. Product series can be used in a wide range of applications, including conventional switch cabinets, stand-alone machinery and industrial systems, as well as information and communications technology.
